Bunnies are really cute, except when they take over your whole town. In South Fargo, North Dakota, big fluffy jackrabbits the size of small dogs showed up a couple of years ago. A woman in this video said that every morning she woke up to see 40-50 of them in her backyard! Why did this happen? In one year a mama jackrabbit can have babies 4 times, with up to 9 baby bunnies in each litter. And if the bunnies have no “predators” — animals who want to eat them — there’s nothing stopping the hopping.

*Wee ones:* How many bunnies can you count in the photo?

*Little kids:* If you see 5 bunnies in your driveway, how many ears do they have? *Bonus:* If the woman sees 8 bunnies under her picnic table, and 1 hops away, then another, then another, what numbers would you say to count down the number of bunnies left?

*Big kids:* If a mama bunny can have 4 litters of babies with 9 bunnies in each, how many bunnies does she have that year? *Bonus:* How many babies would 100 mama bunnies have that year?

Answers:

*Wee ones:* We count 5 whole bunnies, and the back of 1 more.

*Little kids:* 10 ears. *Bonus:* 7 bunnies, then 6, then 5.

*Big kids:* 36 babies. *Bonus:* 3,600 baby bunnies!
